Talk

I will discuss a holographic duality between a family of seven dimensional supersymmetric black holes and superconformal quantum mechanics on the moduli space of SU(N) Yang-mill instantons. The duality predicts a particular exponential growth of degeneracy of BPS states of the quantum mechanics which must reproduce the black hole horizon formula. This exponential growth has been proven...

In recent years there has been an increasing interest in the interplay between amplitudes and cosmological correlators, in particular in the use of amplitudes techniques to constrain cosmological correlators. In this talk, I will give an overview of the formalism of the wavefunction of the universe and how it relates to cosmological correlators. After this, I will review the success of the...

Effective field theory (EFT) is a theory-agnostic approach to understanding how high-energy phenomena would manifest in our low-energy universe. It is an expansion in higher-dimension operators built out of light fields with unknown coefficients. These coefficients can either be constrained through experiment or by demanding consistency with theoretical expectations, such as causal wave...
